Cough, cold, and mild fever can be uncomfortable, especially for children. The common cold and flu are two main causes of cough and cold in kids. Both Allegra and cherry cough syrup can help treat these symptoms. However, it’s best to give only one medication that addresses the needed symptoms, which reduces the amount of medicine given to the child. Make sure she gets plenty of rest, drinks lots of fluids, and consider using a humidifier in her room to help relieve congestion. If her temperature doesn’t go down or if she seems to be in pain, it’s better to consult a pediatrician for proper advice.
